Key Points

To design, synthesize, and structurally characterize four novel symmetrical fused-thiophene chromophores functionalized with triphenylamine for two-photon absorption applications.
Synthesized four symmetrical donor–π–donor (D–π1–π2–π1–D) chromophores incorporating fused-thiophene building blocks.
End-functionalized the conjugated backbones with electron-donating triphenylamine (TPA) units.
Characterized structural and optical properties tailored for two-photon absorption behavior.
Successfully prepared a novel series of four symmetrical fused-thiophene D–π1–π2–π1–D dye architectures.
Integrated electron-rich bis(triphenylaminotetrathienoacenyl) segments to facilitate electronic transitions for non-linear optical absorption.

Abstract

Four new donor–π–donor (D–π ₁ –π ₂ –π ₁ –D) fused-thiophene-based chromophores, end-functionalized with electron-donating triphenylamine (TPA) groups, were developed and characterized for a two-photon absorption study.
